progressposition crash going back from no-swap warning

[Mikel Ward]

Wen triing to install Ubuntu, it gets as far as "15% - Detecting file systems" then fails. It takes me back to the partition screen. After triing to delete the default swap partition (/dev/sdb5) and readd it as a primary partition (/dev/sdb2) then configuring mi uther partitions (/dev/sda1 = /win, /dev/hda1 = /data), the installer presented a warning box saying that I hadnt configured a swap partition with two choices: Go Back or Continue. Wen choozing Go Back, the installer crashed.

I hav three hard disks:
- SATA 1 = /dev/sda
- SATA 2 = /dev/sdb
- PATA 1 (IDE) = /dev/hda

I hav a Windows install on /dev/sda1 (ntfs file system), a data partition on /dev/sdb1 (ntfs file system) and wos attempting to in stall Ubuntu on my secund SATA disk (/dev/sdb).

Mi first SATA disk is configured to boot first in mi BIOS.

The last bit ov the log in the crash box looks like this. Perhaps the Go Back button just dusnt werk (wich wood be a separat bug from the problems with handling mi disk configuration).

Can you attach /var/log/syslog as well please ?

I don't need /var/log/syslog here.

Thanks for your report. After some investigation and thought, I'm going to treat this as a duplicate of bug 51077.
